    I was curious on how to use this setting as regards to finding out if a boiler is over heating or not working up to standard.

    I assume when hot water cycles or cuts out to use this, but im unsure of where to attatch the clamps and what temperatures to look out for when there is a problem.

    cheers

    You need to attach sensors to both flow and return.The differential is then obvious.Manufacturers have their own limits on temp diff but generally under 20*C for most boilers is a rule of thumb.

    First two posts are talking about different things!

    You can use a diff thermostat to measure the difference between CH flow/return, plate HE flow/return and you can also use it to see the rise in DHW in/out ( what is what the OP was alluding to ).

    CPA I is best discussed in the CC.

    Not being funny, but if you need a differential thermometer to figure out if a boiler is overheating or not, you are a long way from running a business on your own.
